Re: How do i work out an average?

Yeah umm, I'm trying to work out the average and it's either my memory is busted or I'm really doing something wrong.

I gotta work out the average of these medal totals for this project.The totals are for the winter olympics each time they're on, and they're the data for Netherlands.9+6+4+0+7+4+4+11+8+9I added those together and the total i got was 124.I then divided that by 10 to get 12.4, but I don't understand how on earth the average isn't within the range of the lowest and highest numbers, i've added the numbers three times now, and there seems to be no differentiating between the results I'm ending up with. The only conclusion I'm drawing is that:1. I'm terribly bad at punching numbers together in a calculator tonight.or2. I have forgotten some sort of trick of the trade with working out the averages.

Is it supposed to be out of the range and have i just made that rule up somehow? Or what?I dunno..Thanks.

Re: How do i work out an average?

OK guys try and estimate the average of this....

In 2006-2007 the HFEA Guide to Infertility tells us that The Number of Patients UNDERGOING IVF is 29688 and that The Number Of CYCLES OF IVF treatment is 38264The question is.. Based on the figures above estimate the number of CYCLES OF IVF that each patient received?

Another one..In 2006-2007 the HFEA Guide to Infertility tells us that The Number of Patients UNDERGOING DONOR INSEMINATION is 3158 and that The Number of CYCLES OF DONOR INSEMINATION is 7350The question is the same as the first question but with these numbers instead.

Lastly...In 2006-2007 the HFEA Guide to Infertility tells us The Number of children born through IVF is 8251 successful births - giving rise to 10242 childrenand that Donor Insemination gave birth to 782 successful births - giving rise to 825 childrenThe question asks you... For both IVF and Donor Insemination why are there more chldren produced compared to the number of successful births

Re: How do i work out an average?

I may be missing something gigantic here but why would you not just do this?

38264 / 29688 = 1.28887092

For the next one:

7350 / 3158 = 2.32742242

I know I am going to get blasted on this. Could there be more children than births because some births have multiple children?You know, twins, triplets, quadruplets etc.

Now what the heck do I know about birthing. But isn't the birth of twins considered 1 birthing. 2 kiddies 1 birthing.The question I am asking you is how do you get 825 children from 792 births without considering twins as 1 birth?

In mathematics, you don't understand things. You just get used to them.If it ain't broke, fix it until it is.No great discovery was ever made without a bold guess.

Re: How do i work out an average?

hi bobbym,

Nice to hear from you.

Sunday; hhhmmmm let's see. It will be dry and sunny. The garden will look tidy now the Spring pruning is done. The rubbish (trash ?) is out for Monday collection along with the recyclables. The Sun has set in the West. The birds have gone to sleep.

Cannot be certain you can extrapolate similar conditions over in Nevada; sure the Sun's behaviour is 'universal' and will do the same but the rest is subject to local boundary conditions.

I sense another NSF grant in the making.

Re: How do i work out an average?

Hi Guys,

Thanks for your reply, but sorry I did not make myself clear enough. I meant how could I get a players average rating from just one match i.e. how good they play just for that match or does the same format apply, because I'm doing shots off/on target, passes complete/incomplete and tackles in possession. Do I just add them all up when I get data and then divide by 5?

Sorry I'm new to this forum sort of thing, but I do appreciate what your doing for me.

Do you really want to say that player 2 is better than player 1 ? I think not.

The raw scores ( 30 and 7 ) give you a better idea of who made the best contributions.

It will be very subjective; that is to say, what you rate as a high mark, might not be what someone else would have given. In the end you'll probably need to adjust the 'weighting marks' according to how things come out.

Have you had a search through the Fantasy Football sites? Maybe someone has already set up such a system.

Bob

ps to bobbym. Oh wow! The Grant ideas just keep coming, don't they?

Re: How do i work out an average?

Hi,

That's great guys, thanks a lot for your help, but I probably be back and ask for more help. Sounds good making your own marking scores, but like you say it's gonna be tricky.

The reason why I need help is because I'm doing a research project at college on anxiety verses performance and I have four tests and they are a profile of mood questionnaire, anxiety test and a mental toughness tests. I was gonna get the averages from the three tests then work out what the players rating was and then average it all of it out, but if you got any better ideas, I'm all ears!!!!

Re: How do i work out an average?

Hi wally187;

Yes, you could make a power formula by weighting which ones you think are more important and that should satisfy your teacher. If you supply your data I can fit it to your results proving that there is a correlation between them. Even if one does not exist!

But, and this is a big but, coming from a town where every third guy is a would be mathematician and statistician. Where people produce and publish power formulas and rating systems every day. No one has ever got rich by following them.

Now for the last point. If Bob Bundy keeps hogging all the grants how can any of my ideas come to fruition?
